Question

На кулю, повністю занурену у ртуть, діє архімедова сила 272 Н. Визначте об'єм кулі. (ρ ртуті =13600 кг/м3)

Answer 1

Ответ:

0,002м³

Объяснение:

p=14600кг/м³

g=10м/с²

V-?

Fарх=pgV

V=Fарх/pg=272/13600×10=0,002м³

Answer 2

Calculating the Volume of a Sphere Immersed in Mercury

To calculate the volume of a sphere fully immersed in mercury, we can use the information provided about the Archimedean force and the density of mercury.

Given: - Archimedean force (F) = 272 N - Density of mercury (ρ) = 13600 kg/m³

We can use the formula for the Archimedean force to find the volume of the sphere.

The formula for the Archimedean force is: F = ρ * g * V Where: - F = Archimedean force - ρ = density of the fluid (mercury in this case) - g = acceleration due to gravity - V = volume of the fluid displaced

Calculating the Volume

We can rearrange the formula to solve for the volume (V): V = F / (ρ * g)

Given: - Archimedean force (F) = 272 N - Density of mercury (ρ) = 13600 kg/m³ - Acceleration due to gravity (g) = 9.81 m/s² (standard value)

Substitute the given values into the formula: V = 272 / (13600 * 9.81)

Calculating the volume: V ≈ 0.002 m³

So, the volume of the sphere fully immersed in mercury is approximately 0.002 cubic meters.

This calculation is based on the provided information and the standard acceleration due to gravity.
